Detailed Description
The embodiment of the application provides a data processing method and related equipment thereof, which are used for controlling the running state of an MCU and a communication assembly mutually.
Referring to fig. 1, a block diagram of a data processing method in the embodiment of the present application includes:
an electronic device comprising an MCU and a communication component.
The MCU properly reduces the frequency and specification of the central processing unit, and integrates peripheral interfaces such as a memory, a counter, a USB, A/D conversion, a UART, a PLC, a DMA and the like, even an LCD driving circuit and the like on a single chip to form a chip-level computer, and different combination control is carried out for different application occasions.
The communication component is a hardware structure for realizing the communication function, can comprise circuit structures such as a communication interface and the like, and is used for supporting GPRS and short message double-channel data transmission.
The communication component and the MCU learn the operating state of the other party by sending commands to each other, and both parties can restart the system of the other party based on the specific operating state of the other party.
Based on the above-mentioned frame diagram, a data processing method in the embodiment of the present application is described below.
It should be clear that, in the cooperative work of the MCU and the communication component in the electronic device, the running state information of the other party needs to be continuously known, so as to provide the current running state information of the other party for the other party and the other party to deal with possible emergency situations in the later period. Based on this, the embodiment of the present application establishes an information interworking mechanism for monitoring the operating states of the other parties with each other and controlling the other party with a poor operating state, please refer to fig. 2, which includes:
201. the MCU sends commands at regular time.
The functional module of the MCU sends a command to the communication assembly at regular time, and the MCU needs to request the communication assembly for the running state information of the communication assembly in order to acquire the running state of the communication assembly. The timing is the interval that the MCU can set the transmission time according to the actual requirement, and the functional module of the MCU continuously transmits one command after another to the communication assembly in the preset time.
It should be noted that the MCU includes N functional blocks, where N is at least 1 and is an integer. The N functional modules of the MCU may send commands simultaneously, or may send commands independently, and the commands are set according to actual requirements, which is not limited herein. Similarly, the sending time intervals of the two modes can be the same or different, and are set according to actual requirements, and are not limited herein.
It should be noted and emphasized that the subsequent steps 202, 203, 204, 205 are only one command for timing transmission of commands to one functional module in the MCU to illustrate the operation content related thereto, and therefore, each command generated by timing transmission of commands to each functional module of the MCU has the same operation content as the subsequent steps 202, 203, 204, 205.
202. The communication component receives the command.
And after the MCU sends out a command regularly, the communication component receives the command.
203. The communication component sends the reply.
It should be noted and noted that the communication assembly also includes N functional modules, where N is at least 1 and is an integer, the total number of the functional modules of the communication assembly is the same as the total number of the functional modules of the MCU, and each functional module of the communication assembly and the functional module of the MCU have an adjustable preset relationship in a one-to-one correspondence.
After the communication component receives the command of step 202, the communication component determines, from the N functional modules of the communication component itself, a corresponding functional module to which the MCU has issued the command, and the functional module issues a response corresponding to the command.
It is to be noted that for each command received by the communication component, the communication component feeds back an answer.
204. The MCU receives the acknowledgement.
The MCU receives the acknowledgement from the communication component.
205. The MCU judges whether to restart the communication assembly.
After the MCU receives the response from the communication assembly, the MCU judges whether the response is received within a preset specified time, if so, the MCU judges that the operation state of the communication assembly is normal, and the MCU does not restart the communication assembly; if not, the MCU judges that the running state of the communication assembly is abnormal, and the MCU restarts the communication assembly.
And the preset time length which is set and adjustable for the MCU and the communication assembly according to the actual situation is set in the set time length.
The specified time length of each pair of functional modules in the MCU and the communication assembly can be the same or different according to the condition that the number of the respective functional modules of the MCU and the communication assembly is more than 1, and is preset according to actual requirements, and the specific time length is not limited here.
The specific process of restarting the communication assembly by the MCU is that the MCU firstly controls the power supply of the communication assembly, then the MCU disconnects the power supply of the communication assembly, and finally the MCU starts the communication assembly.
It should be noted and reiterated that in steps 201 to 205, steps 202, 203, 204 and 205 are triggered by a sequential association of a command in step 201, and each command generated by sending a command periodically to step 201 corresponds to the action of generating steps 202, 203, 204 and 205.
In the above steps 201 to 205, the MCU continuously sends commands to the communication components, the communication components must feed back responses to each command to the MCU, and the MCU obtains the operating status information of the communication components by determining the received responses, so that the MCU has a function of monitoring the communication components. And when the MCU learns that the communication assembly is in the abnormal operation state through judgment, the communication assembly is restarted, so that the MCU has the capacity of controlling the communication assembly.
206. The communication component sends commands in a timed manner.
This step is similar to step 201 and will not be described herein again.
207. The MCU receives the command.
This step is similar to step 202 and will not be described herein.
208. The MCU sends a reply.
This step is similar to step 203 and will not be described herein.
209. The communication component receives the reply.
This step is similar to step 204 and will not be described here.
210. The communication component judges whether to restart the MCU.
This step is similar to step 205 and will not be described herein again.
Similarly, in the above steps 206 to 210, the communication component continuously sends commands to the MCU, the MCU sends a response to each command to the communication component, and the communication component obtains the running state information of the MCU by determining the received response, so that the communication component has a function of monitoring the MCU. And moreover, the communication assembly restarts the MCU when knowing that the MCU is in an abnormal operation state through judgment, so that the communication assembly has the capability of controlling the MCU.
It should be noted that the execution sequence of steps 201 to 210 is not fixed after the execution sequence meets the necessary time logic, for example, the execution sequence of steps 201 to 205 may be after steps 206 to 210, steps 201 to 210 may also be executed synchronously with steps 206 to 210, steps 201 to 205 may also be executed alternately with each of steps 206 to 210, and the specific details are not limited herein.
Further, in an actual process, although the number of the functional modules of the MCU and the communication module in the electronic device is the same, the number of the functional modules may change according to actual requirements, which is described below:
the number of functional modules of the MCU and the communication assembly is respectively 1:
in this embodiment, an MCU in an electronic device is used as a description object for explanation, and peer communication components in the electronic device have similar operation contents. Wherein, both sides of MCU and communication subassembly have a functional module respectively, correspond to each other. In addition, in this embodiment, the MCU first determines whether the communication module operates normally, and then determines whether the MCU operates normally, referring to fig. 3, including:
301. the MCU sends a first command to the communication component in a timing mode.
In order to obtain the operating state information of the communication component, the MCU needs to continuously request the communication component. The functional module of the MCU sends the first command to the communication component at regular time through preset time, so that continuous first commands are formed in time and used for triggering the communication component to correspondingly respond to each continuous first command. The time interval of the preset time is preset according to the actual situation.
302. The MCU receives a first response sent by the communication component based on the first command.
And after the communication assembly receives each first command, the functional module of the communication assembly sends a first response corresponding to the first command to the MCU, and the MCU receives the first response.
It should be noted that, in step 301, for each first command sent by the MCU functional module, the functional module of the communication component corresponding to the first command needs to feed back a first response corresponding to the first command to the MCU.
303. And the MCU judges whether the communication assembly normally operates according to the first response.
The MCU calculates the time length of the sending and receiving processes based on each received first response and the first command corresponding to the first response, and compares the time length with the preset time length so as to judge whether the running state of the communication assembly is normal. Because, when the functional module of the communication component is in an abnormal state, its response may be delayed due to the abnormal operating state. The preset duration is set or adjusted in advance based on actual conditions, and is not limited herein.
Specifically, the MCU determines whether the first response is received within a preset time period, and if the first response received by the MCU is received within the preset time period, it indicates that the operation state of the communication module is normal, and executes step 307; if the first response received by the MCU is not received within the preset time period, it indicates that the operation status of the communication component is abnormal, and step 304 is performed.
304. The MCU restarts the communication component.
The MCU judges that the first response is not received within the preset time, controls the power supply of the communication assembly, disconnects the power supply of the communication assembly and restarts the communication assembly.
305. And the MCU receives a second command sent by the communication component at regular time.
Similarly, in order to know the running state information of the MCU, the communication component needs to continuously request the MCU. And the functional module of the communication assembly sends the second commands to the MCU at fixed time through preset time so as to form continuous second commands in time, and the MCU receives each second command.
306. The MCU sends a second reply to the communication component based on the second command.
And after the MCU receives each second command, the functional module of the MCU sends a second response corresponding to the second command to the communication component, and the communication component receives the second response. And in the later period, the communication assembly calculates the time length of the sending and receiving processes based on each received second response and the second command corresponding to the second response, and compares the time length with the preset time length so as to judge whether the running state of the MCU is normal.
It should be noted that, for each second command received by the MCU, the MCU functional module needs to feed back a second response corresponding to the second command to the communication component. Also, like step 302, the functional modules of the MCU have a pre-correspondence relationship with the functional modules of the communication assembly. Step 305 and step 306 may be executed simultaneously with or before or after any of steps 301 to 304, without being limited to being executed after step 304.
In this embodiment, the MCU and the communication module of the electronic device have 1 functional module respectively, and the MCU determines whether the communication module operates normally first, and determines whether the MCU operates normally after the communication module, and the following numbers of the two functional modules in the electronic device are 3 respectively, and the communication module determines whether the MCU operates normally first, and determines whether the communication module operates normally after the MCU, and the following description is made:
secondly, the number of functional modules of the MCU and the communication assembly is respectively 3:
in this embodiment, a communication component in an electronic device is taken as a description object for explanation, and an opposite-end MCU in the electronic device has similar operation contents, where both the MCU and the communication component have 3 functional modules, and correspond to each other. In this embodiment, the determining whether the MCU is normally operated by the communication module first and then by the MCU includes:
401. the communication component sends a first command to the MCU in a timing mode.
This step is substantially similar to step 301, except for slight changes caused by the functional block 3 of the communication assembly. On this basis, the variant is that the 3 functional modules of the communication assembly periodically send the first commands to the MCU according to their respective preset times, also forming respective successive first commands in time. The time intervals of the respective preset times may be the same, may be different, and are not limited herein.
402. And the communication component receives a first response sent by the MCU based on the first command.
After the MCU receives each first command, the functional module of the MCU sends a first response corresponding to the first command, and the communication component receives the first response.
The MCU functional module for sending the first response corresponding to the first command is corresponding to the functional module of the communication component for sending the first command in advance. That is, 3 functional modules of the MCU and 3 functional modules of the communication component are corresponded in advance. In each pair of functional modules, one functional module in the pair sends continuous first commands at regular time, and the other functional module in the pair sends first responses to the first commands; it can also be said that, by this pre-correspondence, each first command of the respective functional module of the MCU is answered one by the corresponding functional module in the communication assembly.
It should be reiterated that, for each first command sent by the functional module in the communication component in step 401, the functional module of the MCU needs to feed back a first response corresponding to the first command to the communication component.
403. And the communication component judges whether the MCU normally operates according to the first response.
And the communication component calculates the time length of the sending and receiving processes based on each received first response and the first command corresponding to the first response, and compares the time length with the preset time length so as to judge whether the running state of the MCU is normal. Because, when the functional module of the MCU is in an abnormal state, its response will be delayed due to the abnormal operation state. Each pair of preset time lengths is set or adjusted in advance based on actual conditions, and is not limited herein. The preset time lengths of different pairs of function modules may be the same or different, and are also set or adjusted in advance based on actual situations, and are not limited herein.
Specifically, the MCU determines whether the first response is received within a preset time period, and if the first response received by the MCU is received within the preset time period, it indicates that the operation state of the communication module is normal, and performs step 407; if the first response received by the MCU is not received within the preset time period, it indicates that the operating status of the communication component is abnormal, and step 404 is executed.
404. The communication component restarts the MCU.
This step is similar to step 304 and will not be described herein.
405. And the communication component receives a second command sent by the MCU at regular time.
This step is generally similar to step 305, except for the slight changes caused by the functional block of the MCU being 3. Based on this, the change is that the 3 functional modules of the MCU periodically send the second commands to the communication component according to their respective preset times, thereby forming consecutive second commands in time, and the communication component receives each second command sent by the 3 functional modules of the MCU.
406. The communication component sends a second reply to the MCU based on the second command.
And after the communication assembly receives each second command sent by 3 functional modules in the MCU, the functional module corresponding to the communication assembly sends a second response corresponding to the second command to the MCU, and the MCU receives the second response. And in the later period, the MCU calculates the time length of the sending and receiving processes based on each received second response and a second command corresponding to the second response, and compares the time length with the preset time length so as to judge whether the running state of the communication assembly is normal.
It should be noted that, for each second command received by the communication component, the functional module corresponding to the communication component needs to feed back a second response corresponding to the second command to the MCU. Similarly, as in step 402, the 3 functional modules in the MCU also have a pre-correspondence relationship with the 3 functional modules in the communication component. Further, steps 405 and 406 may not be limited to be executed after step 404, and may be executed simultaneously with or before or after any of steps 401 to 404.
It is understood that the execution sequence of the steps in fig. 3 and 4 is not fixed. When the MCU and the communication component judge and control the operation of the other side, the MCU and the communication component can also carry out the steps of the method.
In this embodiment, a case that the MCU and the communication module of the electronic device respectively have 3 corresponding functional modules and the communication module first determines whether the MCU normally operates or not, and then determines whether the communication module normally operates or not is described, where a structure of a single-chip microcomputer of the electronic device is described below with reference to fig. 5, including:
